How to Rank in AI Search (ChatGPT, Perplexity, Google AI Overviews)

By Jeroen 10 min read
TL;DR: AI search engines (ChatGPT, Perplexity, Google AI Overviews) don't have a separate ranking algorithm you can game. They pull from authoritative web content. To appear in AI answers, you need: content that directly answers questions (answer capsule at the top of each page), structured data that communicates what your page is about, E-E-A-T signals that establish your credibility, and fast-loading pages that AI crawlers can access. Traditional SEO and AI search optimization are more complementary than they are separate disciplines.

If you've noticed ChatGPT and Perplexity appearing alongside Google in your browser, you've already seen the shift. A growing number of people, including your potential customers, are starting their research in an AI tool rather than a search engine.

The question everyone is asking: "How do I show up there?"

The answer is less mysterious than the marketing around "AI SEO" suggests. Here's what actually drives AI search visibility.

AI search doesn't just return links. It recommends specific businesses by name. The businesses it recommends aren't random.

What "AI Search" Actually Is

There are three distinct surfaces you should understand:

Google AI Overviews

These are the AI-generated summaries that appear above traditional blue links for many informational queries. Google generates these by synthesizing information from multiple web pages it has already indexed and ranked. The pages cited in an AI Overview are almost always from the top 10 organic results for that query, which means ranking in Google remains the prerequisite for appearing in AI Overviews.

ChatGPT (with web browsing)

When ChatGPT uses web browsing (available in the Plus and higher tiers), it retrieves live web content to answer questions. It prioritizes pages that are authoritative, well-structured, and directly answer the query. The Bing search index underlies ChatGPT's web retrieval, which means Bing indexation and authority signals matter for ChatGPT citation.

Perplexity

Perplexity is a purpose-built AI search engine that retrieves from the live web and cites its sources explicitly. It tends to favor pages with high content quality, direct-answer formatting, and credible citation chains within the content itself. Perplexity's approach is the most transparent of the three: it shows exactly which pages it pulled from for every answer.

Why Traditional SEO Isn't Enough

Ranking #5 on Google for a keyword doesn't guarantee you'll appear in AI answers for the same query. AI engines don't just look at position, they evaluate content quality. A page that ranks #5 through technical optimization and link building but has vague, hedged content may be bypassed by a page that ranks #8 but has a clear, direct answer in the first paragraph.

According to Google's AI Overviews documentation, AI Overviews pull from a broader set of pages than just the #1 result, and content structure is a significant factor in what gets cited. The pages that appear in AI Overviews consistently use clear headings, direct answers, and structured data.

The 5 Factors AI Search Engines Weight

1. Direct Answers Near the Top of the Page

AI engines extract the most relevant passage from a page, not the whole page. If your answer to the implied query is buried in paragraph 8 after three paragraphs of context-setting, the AI may skip your page in favor of one that leads with the answer.

The pattern that works: lead every page and every section with the direct answer, then support it with context, evidence, and nuance. The "inverted pyramid" journalism structure that puts the most important information first is exactly what AI engines prefer.

2. Structured Data (Schema Markup)

Schema markup communicates what your page is about in a language that both Google and AI engines can parse without having to infer meaning from prose. The schema types most relevant for AI visibility:

  • FAQPage: Each question-answer pair on your page becomes a discrete retrievable unit. AI engines can pull individual FAQ answers even if the rest of your page isn't cited.
  • Article or BlogPosting: Communicates content type, publication date, and author to AI engines, which weight content freshness.
  • LocalBusiness: Tells AI engines where your business operates, what it does, and how to contact it, which is the prerequisite for appearing in local AI answers.
  • HowTo: Step-by-step processes that AI engines can extract and present as instructions in their answers.

3. E-E-A-T Signals

Google's E-E-A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness) was designed for human quality raters, but AI engines apply similar logic. Pages that display author credentials, cite credible sources, and are referenced by other authoritative sites are more likely to be selected as sources.

For local businesses, E-E-A-T means: your Google Business Profile is complete and matches your website, your staff pages display professional credentials, your content cites industry sources rather than making unsupported claims, and other local websites reference your business (reviews, local press, directory listings).

"Sites that demonstrate first-hand expertise and depth of knowledge on a topic are exactly the kind of sites we want to reward."

4. Page Speed and Core Web Vitals

AI search crawlers, like Google's crawlers, skip pages that are slow to load. If your page takes 5 seconds to load, an AI tool may time out before retrieving the content. Beyond crawlability, Google's Core Web Vitals scores affect whether pages are considered "high-quality" in the first place. Pages with poor LCP (Largest Contentful Paint) and CLS (Cumulative Layout Shift) scores get deprioritized in quality assessments.

5. Content Freshness

AI engines weight recently updated content for queries where currency matters. A page about AI search tools that was last updated in 2022 is less likely to be cited than one updated in 2026. Adding a "last updated" date and keeping high-priority pages current is a practical AI visibility tactic, not just good SEO hygiene.

The Answer Capsule Technique

One of the most effective tactical changes you can make for AI search visibility is adding an answer capsule to every page with informational intent. This is a styled box at the top of the page that directly answers the implied query in 2-4 sentences.

Example: A page targeting "how long does it take to build a website" would open with a box that says: "A basic small business website takes 2-4 weeks to build. A custom site with multiple pages and custom functionality takes 6-12 weeks. Here's what determines the timeline."

AI engines extract this box and cite it directly in their answers. You get the citation even if the user never reads the rest of your page. See how we apply this on our own service pages, including our answer engine optimization pages.

Local Businesses in AI Search

Local AI queries are growing. People are asking ChatGPT and Perplexity "best accountant in Oakland," "top dental practice San Francisco," and "who does pest control in Sacramento." AI engines answer these by pulling from:

  • Google Business Profile data (your GBP listing is AI-readable)
  • Review content from Google, Yelp, and other platforms
  • Your website's LocalBusiness schema markup
  • Local citations and directory listings that mention your business in context

For local businesses, AI search visibility is an extension of the same GBP and local citation work that drives traditional Map Pack rankings. A well-optimized GBP with strong reviews and accurate NAP data feeds both Google Maps and AI engines that query local business information. This applies across all the verticals we work with: healthcare practices, law firms, professional service firms, and restaurants.

AEO vs. SEO: Complementary, Not Competing

Answer Engine Optimization (AEO) isn't a separate strategy from SEO, it's an extension of it. The content that ranks well in traditional Google search tends to rank well in AI search too, because both reward authoritative, well-structured, directly useful content.

The additional elements AEO requires (answer capsules, FAQ schema, direct-answer formatting) are incremental changes to existing content, not a ground-up rebuild. The businesses that win in AI search will be the ones that treat it as part of their overall content quality investment, not as a separate tactical campaign.

Voxel Phase focuses on this intersection of traditional SEO and AI visibility. Our answer engine optimization service, AEO agency approach, and focus on generative engine optimization cover the full scope of what it takes to appear in both Google and AI-generated answers.
